SELF-DISCHARG'ING CAR.

'Patented Jury a, i922.

To @ZZ fic/wm t may concern.'

Be it known that I, KARL BARTH, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in- Self-Dischar,f;'ing

toward either side about one of two later'-` ally disposed axes, it being a special object of the invention to simplify the construction of cars of this type.

The invention will be further described with reference to the accompanying drawing which shows one embodiment of the subject matter of the invention by way of eX- ample and in which:

Fig. l is a diagram disclosing in cross sect-ion the car when ready for loading,

Fig. 2 is a part sectional view of the car after eecting a discharge toward the left, and

Fig. 3 is a part sectional view of the car after effecting a discharge toward the right.

Referring to these drawings, the two end walls A1 of the car are rigidly Xed in parallel to each other on the underframe A thereof. In addition, there are arranged on the said underframe A both at the front and the rear end of the car two sockets A2 disposed symmetrically with respect to the middle longitudinal plane of the car. Said sockets serve to lodge two shafts B which extend over the entire length of the car and are operated if desired from the ends of the latter by means of levers G, which may be fixed to the end walls A1 of the car in one position by means of key bolts H. To each of the shafts B there are rigidly connected crank arms b1 which are articulated to the bottom C of the car by means of links D. To the underframe A there are furthermore provided abutments a? projecting into the path of the crank arms b1 and which, when the crank arms come to bear up against them (Fig. l), allow the said crank arms to execute a rotation only in the inward direction. Stops c1 are provided for the links D at the bottom C of the car, which in their turn, when the said links bear up against them, likewise only permit these links to carry out an inward rotation. 0n the bottom C there are firmly arranged supporting surfaces c2 destined, on the discharging motion of the bottom C, to settle down on the abutments a3 and thus to limit said discharging motion.

Each of the two side walls E of the car is provided, in the known manner, at its lower edge with bearings el, open at the bottom which, when the car is ready for charging, engage journals c3 arranged on the bottom C. l/Vith its upper edge each of the side walls reposes in open bearings t4 of the end walls A1 (Figs. 2 and 3). The side walls E are guided in their movements by means of links F lodged on the end wallsAl.

7When the car is ready for loading the described parts assume the position relatively to each other disclosed in Fig. l. The crank arms b1 and the links D then are disposed parallel to the middle'longitudinal plane of the car and their longitudinal directions c0- incide so that the weight of the movable parts of the car and the weight of the load will exert no rotary moment on the shafts B. Any accidental inward displacement of the crank arms b1 in the direction denoted by the arrows fr, (Fig. l) is prevented by the key bolts H on the levers G, whereas a movement in the outwardf'direction of the said crank arms is rendered impossible by the abutments a?. As a result of the two shafts B, and therewith of the crank arms b1 mounted thereon, being fixed in the aforesaid manner, the bottom C is likewise firmly secured in its position. For in this case the bottom could only possibly carry out a movement if on the one side of the middle longitudinal plane the links D were enabled to rotate outward relatively to the bottom, such a movement of the links D being, however, prevented by the stops c1.

When the car is to be discharged toward one particular side, say, for instance, toward the left, then, the key bolt I-I on the left side having been released, the shaft B disposed to the left of the longitudinal plane of the car is rotated in the direction denoted by the appropriate arrow a: (Fig. l). As soon as the crank arms 1 fixed to the shaft B have been rotated for a certain small distance, the left-hand system comprising the cranks 1 and the links D collapse under the weight of the load and the bottom C attains the discharge position (Fig. 2) by carrying out a rotation within the link connections existing between the cranks b1, disposed to llO the right of the middle longitudinal plane of the car and the respective links D which are fixed relatively to the bottom by the stops c1. As the bottom (l begins to rotate, the journals 03 thereof, which are located to the left of the middle longitudinal plane of the car, disengage from the bearings c1 of the left-handside Wall E. In the course of the subsequent discharge motion, this side Wall E then remains suspended in the known manner in the bearings at, Whereas the righthand` side Wall E is raised. Upon the `ter-- mination of the discharge motion, the lei'thand supporting surfaces G2 of the bottom lbear against the abutments a3 ofthe underframe A and `thus secure the bottom C relatively to the underframe.

The manner of returning the car into the l state ready 'for loading after the discharging operation has been effected, as also the method ot discharging the car toward the opposite side (Fig. 3) will require no further explanation afterV the foregoing description.

l claim: t t

l. A self discharging receptacle comprising a rotatably disposed bottom., a frame structure, said bottom` articulated to said frame structure by means of link devices,

the elements of Which devices when said receptacle is in loaded position are substantially parallel each to each-to form a substantially linear support for said bottom, and abutments for said link devices permitting a collapsing action of said linlr devices only toward the longitudinal center line of said receptacle. r Y K 2. A self discharging receptacle comprising a rotatably disposed bottom, a frame structure, said'bottom articulated to said trame structure by means of'link devices, the elements of which devices when said receptacle is in loaded position are substantially parallel each to each to form a substantially linear support tor said bottom, andabutments for said linkdevices permitting a collapsing action of said link devices only toward the longitudinal center line of said receptacle, said trame structure having allotments co-operating With said bottom, when said bottom isf rotated on the collapse of one of said link devices. t
